PUMP.

Application led September 21, 1925. Serial No. 57,635.

This invention relates to new ful improvements in a pump.

One object of the invention is to produce a pump of the character described embodying a working barrel and a traveling valve controlled, plunger therein, which works through packing within the barrel around said plunger, and further embodies means through which the packing may be adjusted about the plunger.

Another object is to produce a pump of the character described embodying .a sucker rod, through which the plunger is reciprocated, and through Vwhich the packing may be adjusted, about the plunger to tighten, or relieve said packing.

A furthe-r feature of the invention is Vto provide an upward ,type of packing and means for preventing its displacement.

7With the above and other objects in view this invention has particular relation to certain novelfeatures of construction, operation and arrangement of part-s, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figures 1 and 2 show .side elevations' of the upper and lower ends respectively, of the pump, shown partly in section.

Figure 3 shows a cross sectional view thereof, taken on the line 3 3 of Figure 2.

Figure 4 shows a cross sectional'view, taken on the line 4-4 of Figure 2.

Figures 5 and 6 show respectively upper and lower ends of aslightly modiiied form of the pump.

Figure 7 shows across sectional view, taken on the line 7-7 of Figure 6, and

Figure 8 shows a cross sectional view tak-en on the line 3-8 ot Figure 6.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each ott the tigures, the numeral 1 designates the well and usecasing and the numeral 2 designates the pump tubing to the lower end of which a working barrel is attached. In the form shown in Figures 1 to 4this barrel is formed with three sections, an upper section 3, an intermediate section 4 and a lower section 5. The upper section is threaded onto the lower end of the tubing and the respective upper and lower ends 'of the intermediate section are threaded onto the adjacent ends ott the upper and lower sections 3 and 5. The lower end of the lower section 5 is threaded into a coup-ling 6 and within the barrel there is an elongated gland 7, whose upper end has an .annular externa-l rib 8, which interlocks with an annular rib 9, carried by the coupling 4. The upperY end or" the gland supports a metal ring 10 which in turn supports the packing 11, which is Within the pump barrel around the plunger 12. This packing supports a Spool like spacer 13 whoseupperend supports a metal ring 14, which also .supports a packing 1 5, around said plunger. The upper end of the packing 15-abuts the annular internal rib 16, within the barrel section 3.

The lower end of the gland 7 has a Vertical, polygonal bearing 17 `and thel lower end or the plunger is extended and formed to lit through said bearing '17, when the plunger is in lower position. This arrangement forces the gland to turn when the plunger is turned. The gland is connected to the coupling 6 by left hand threads and in order to tighten up the packing the sucker rod 18 which is connected to the plunger, is turned to the right and the gland 7 will be correspondingly turned and thereby forced up against thev packingr 11,

to tighten the .same and cause it to ytit more closely about the plunger, and in a like manner the spacer 13 will be forced up again-st the packing 15 to tighten it also.

In the form shown in Figures 5 to 8 the pump barrel is composed of twv sections, an upper section 19 and a lower Section 2O connected by an internally left hand threaded coupling 21. In this form the gland 7 is threaded through the coupling 21 and its upper end abuts the metallic ring 10 which in turn supports the packing 11; the spacer 13 and packing 15 or' this form are supported and `arranged in a manner similar to these parts shown in Figure 1. In Figure 5 there is a metal ring 22 supported by the packing 15 and abutting the internal shoulder 23 at the upper end of the barrel.

The lower end oi' the gland 7 also has the polygonal bearing 17 to receive the correspondingly shaped, extended lower end of the plunger. This end of the plunger is of such length that it will not be withdrawn from said bearing upon up stroke of the plunger and will always be in position to turn said gland.

The packing, in this form may be tiohtened up in the same manner as above explained.

packing inay be crniedl of rubber, rubber-4 ized fabric, or other suitable material,- and is preferably substantially square in cross section, and has a Steel Wire core 0i Which tends to hold the saine expanded againstV the barrel and thus holds the packing in place, in the barrel, when the plunger is Withdrawn. The packing is further retained in place by upper and lower retain'- .ing rings 25, 25, which abut the packing ends and are provided with inside retaining 'flanges 26, 26 vwhich lit- Within the pack-V ing. Y

js/"haiti claini is i l; A puinp including a barrel, a plunger therein, packing in the barrel around the plunger, ineans Within-the barrel beneath the packing and operatively connected With,'and adapted to be rotated by the plunger, through which the packing inayv be adjusted about the plunger.

2. A puinp including a Working barrel ,a plunger therein, packing in the barrel about the` plunger, end abutments eoniining threaded connection with the barrel and also being operatively connected with the plunger and being adapted to be rotated therefrom.

3. A puinp including a barrel, a plunger therein, packing" in the barrel around the plunger, a gland having a threaded connection with the barrel and abuttingY the lower end ol' the packing, said plunger and gland having part-s adapted to interlock and through which the rotation of the alunger i ill be imparted to'. the gland.

In testiinon whereof I have signed inv naine to thi-s specification.
